ABSTRACT:
In a radiation emitting device, particularly in a radiation treatment device, the actual radiation delivered to an object via a radiation beam is adjusted dependent on the dimensions of an opening in a plate arrangement provided between a radiation source and an object so that the radiation output has a constant output factor over an irradiation field, regardless of the size of the opening. The output factor is defined as the ratio of the radiation output in air with a scatterer (such as shielding plates) in the beam path to the radiation output without the scatterer for a reference field.
